Repealing the sequestration economy could gain 1.6 million jobs and increase GDP by as much as 1.2% in FY 2014. A report by Macroeconomic Advisers, LLC finds that discretionary spending cuts since 2010 have reduced annual GDP growth by 0.7 percentage points since 2010 and raised the unemployment rate 0.8 percentage points, representing a cost of 1.2 million jobs. Goldman Sachs released the chart below in 2012 showing how federal policy since 2010 has been acting to slow growth.

The intellectual backing for tough austerity has been hammered this year. Recently, the IMF warned that private debt is slowing growth far more than government debt. Earlier this year a UMass-Amherst graduate student tried to replicate the results of the famous study by Carmen Reinhart and Kenneth Rogoff that purported to show how debt dragged on growth, he found it riddled with errors

Although the famous spreadsheet error (wherein RR failed to include cells in a calculation) made the biggest splash, the deeper error was a logical fallacy: Post hoc ergo propter hoc. Economists like Paul Krugman and Brad Delong argue that government debt doesn't slow economic growth but rather slow economic growth causes the government to take on more debt. Research by Miles Kimball and Yichuan Wang find that this is the actual causation, so there is no evidence or logical reason to believe that reducing government debt right now will help the economy grow.

According to CBO's projections under current law, the contribution of automatic stabilizers to the federal budget deficit, measured as a share of potential GDP, will rise slightly in fiscal year 2013, to 2.5 percent. That contribution accounts for about half of the estimated deficit this year. The contribution will remain at 2.5 percent of potential GDP in 2014, accounting for roughly three-quarters of the projected deficit next year.

CBO expects that the budgetary effects of automatic stabilizers will remain large because of the continued weakness in the economy, which is caused in part by the fiscal tightening that is occurring in calendar year 2013 under current law.

Half of the deficit in 2013 this year is due to automatic stabilizers (the reduction in revenues and increase in spending that occurs when an economy enters a recession). If the economy was in full swing then, the deficit would immediately be halved.
